Anyone know if the Evo X Center Punch vanes are 1 degree or 4 degree offset? I want to buy a fletching jig just in case I have to re-fletch any of my bolts, but I am not finding much that isn't either helical or straight. I did find a few that specified 1 or 4 degree offset though. Can Randy or anyone else chime in on jig options for these bolts? Thanks in advance!
